This is a discussion on Bug#446964: linux-image-2.6.18-5-686: kernel BUG at fs/exec.c:1459! - Debian ; Package: linux-image-2.6.18-5-686
Version: 2.6.18.dfsg.1-13etch4
Severity: normal
System was rebooted 2 days ago due to kernel security update,
I was trying to read some mail using mutt when app crashed
and kernel left info about some problem:
Oct 16 21:31:30 server ...

System worked without problems (and reboot) for last couple of months acting
as network gateway doing NAT, proxy (squid), small web server and windows file
server (samba). After this bug system seems to work ok, only there's this
mutt process stuck in D state - few MB wasted, but there's plenty of ram left
